This paper analyzes the factors of FDI inflows in ASEAN countries over the period 1991 to 2009. The results indicate that the market size, trade openness, quality infrastructure, human capital, labor productivity are the main factors that have positive impacts on FDI inflows. Additionally, exchange rate policy, real interest rate, political risk and corruption also affect FDI inflows. Surprisingly, the cheap labor does not help to attract FDI to the region, because foreign investors are particularly interested in labor productivity. This study also shows that the Asian financial crisis in 1997 affected the amount of FDI inflows, but not on the nature of FDI inflows in the region.
